Description

Space shuttle backing-up screw
Technical field
The utility model relates to screw technique field, especially a kind of space shuttle backing-up screw.
Background technique
Screw on space shuttle is in real work, external load has vibration, change, material at high temperature creep etc. that frictional force can be caused to reduce, in screw pair, positive pressure is zero in a certain pop-off, frictional force, thus scyewed joint is loosened, as through repeated action, scyewed joint will relax and lose efficacy.Therefore, locking design must be considered, otherwise the normal work of complete machine or parts can be affected, even cause the accident.
Model utility content
The technical problems to be solved in the utility model is: the problem loosened in order to the screw attachment solved on space shuttle, now provides a kind of space shuttle backing-up screw.
The utility model solves the technological scheme that its technical problem adopts: a kind of space shuttle backing-up screw, comprise threaded stem and nut, described threaded stem is fixedly connected with nut, also comprise and there is the protruding anti-pinecone, the position that described nut does not overlap with threaded stem is provided with the axial hole matched with the described anti-pinecone, described through hole is provided with screw thread near fore-end, screw is provided with in shown through hole, described screw top is fixedly connected with the anti-pinecone, the described anti-pinecone and described through hole are slidably connected, the movement of bead can be driven by rotary screw, loosening of screw is prevented by bead and the spacing of connected piece.
Further, described projection is provided with guide rail, and the inwall of described through hole is provided with the axial notch matched with described guide rail, and the relatively described groove of described guide rail slides.
Further, described nut is provided with counter sink, and described counter sink is interior hexagonal, and interior hexagonal strengthens turn tautness, and Safety performance increases.
Preferably, described screw top and locking ball bonding connect.
The beneficial effects of the utility model are: the utility model snaps into be connected in circular trough that component preset by being provided with the anti-pinecone that can control to slide on nut, play the effect preventing screw rotation locking, the utility model structure is simple, and successful, plays extraordinary locking effect.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is space shuttle backing-up screw schematic diagram of the present utility model;
Fig. 2 is the schematic diagram of embodiment 1.
In figure: 1, nut, 2, counter sink, 3, guide rail, 4, screw, 5, through hole, 6, protruding, 7, the anti-pinecone, 8, threaded stem, 9, circular trough, 10, component, 11, space shuttle body.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
Embodiment 1
A kind of space shuttle backing-up screw as shown in Figure 1, comprise threaded stem 8 and nut 1, threaded stem 8 is fixedly connected with nut 1, also comprise the anti-pinecone 7 with protruding 6, the position that nut 1 does not overlap with threaded stem 8 is provided with the axial hole 5 matched with the anti-pinecone 7, through hole 5 is provided with screw thread near fore-end, screw 4 is provided with in through hole 5, screw 4 top is welded with the anti-pinecone 7, protruding 6 are provided with guide rail 3, and the inwall of through hole 5 is provided with the axial notch matched with guide rail 3, and guide rail 3 confronting grooves slides, nut 1 is provided with counter sink 2, and counter sink 2 is interior hexagonal.
Above-mentioned screw concrete utilization is as follows on space shuttle:
First being screwed in by screw is as shown in Figure 2 fastened on space shuttle body 11 by component 10, when screwing, the circular trough 9 that the anti-pinecone 7 on nut 1 is just just good to component 10 surface programming, screw 4 now in rotary nut 1 through hole 5, screw 4 drives the anti-pinecone 7 to be pressed into circular trough 9, screw due to the spacing of the anti-pinecone 7 can not rotation, play locking effect.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
